#79 of 86 Thinking of buying...
Apr 19, 2012 (7:48 am)
Hello! Im thinking of buying a used 2005 BMW Z4 w/ 42,000 miles on it, the carfax was clean but i havent own a bmw before much more a z4 i'm wondering at what point you started doing repairs on your z4 at how many miles? should i even consider buying a z4 w/ 42,000 miles on it? im thinking of driving it for two more years before i trade it in, but i def. dont want to spend money on repairs, just thought i'd ask owners and do my due diligence. Thank you so much!

BMW Z4's don't require the heavy hitting major service interval until 100K. Until 50K miles or 4 years - all maintenance including oil changes (except rotors, brake pads and tires) is free. As you must know, your 2005 is outside the free service BMW warranty by 2 years now.
Still, 42K is very low mileage. Probably the only thing the car should need (if not already done) is brake pads, rotors and tires - possibly an oil change. You don't have to go to BMW for these repairs. You can save from 10-50% off what the dealer's typically charge by finding a good mechanic. Get four good A A A rated 50K non-run flat all season tires off the internet for under $400. Balanced and mounted for $40 to $80 depending where you get them mounted. Be careful where because BMW rims scrap easily unless a touchless tire mounting system is used.
Next comes regular service. A Lube/Oil/Filter I recommend every 7,500 miles (ignore the 15,500 mileage counter for service - it doesn’t include LOF). You may hear the car can go 15,500 miles between synthetic oil changes - it really depends on how you drive, but you're likely to experience valve or other problems as the car nears 70K-100K if you neglect regular LOF. An LOF costs $100 or $200 at most BMW dealerships. Four rotors and pads is going to cost you something like $800, but you can get it done for hundreds less if you know a good mechanic, a friend or do it yourself. Every 15K miles, the car needs a full service which run $200-$400 (depending where you go to have it done). The major service is required typically every 30K miles. This runs about $1,000 to $2,000.
After about 7 years, the head light cover gaskets dry out and take a set. If a bulb burns out, you need to replace either the gasket or the headlight cover that comes with a new gasket. Otherwise, you'll be replacing bulbs every 3-6 months as moisture keeps collecting in the headlight. You may also need a new battery. I replaced mine for around $140 and it's twice the battery that comes stock with Z4s.
There’s a reason that BMW offers free service the first 50K or 4 years – they are bloody expensive cars to maintain. I have put about 25K on my Z4 a year the last 6 years. I can tell you that the Honda Civic I drove for the 10 years prior cost me about a quarter of what this car does in maintenance. …but at the same time – this car is 20 times more fun to drive! (even more so as a daily commuter.)
Way I figure it, you only live this life once - you might as well enjoy it. Treat others well, but always be true to yourself. Good Luck.

Thank you so much for the advice! funny you mentioned that you use to own a honda, that's me right now, and i've been driving the same honda civic for the past 10 years w/ little to no repair expense. But i figured, i might as well go for the fun car before i start popping kids and have to buy the mommy SUV lol so i was torn between sticking w/ the new Honda Civic for around $18K or this BMW z4 w/ 42k miles for $16,999. Like i said, im only planning on enjoying it for two/three years tops averaging 10K per year (thats how much i drive now). Again, thanks so much! i really apreciate the insight!

To add to the list (personal experience, 2005 Z4):
- new battery
- new starter
- variety of belts
- light fixture housings
Fun to drive but echo the high TCO of BMWs. Be sure to look for sources other than auth BMW service centers for big discounts on parts and labor.

Hi there, I bought a 2004 Z4/Sport mode 6-speed July 2012, with 48k on it, LOVING IT! Have done front brake pads, replacing rear tires today with non run flats, can't fathom the thought of replacing OEM run flats every 12-15k. We'll see how that goes when I pick it up tonight. This car is THE most fun I've had on four wheels, and I had a 3-series ragtop back a ways. Some mornings, I just drive right by the office and keep driving for a bit, so nice!

If you only drive it when the weather is nice with less than 5,000 miles a year on your sweet Z4, use the OEM run flats.
If this is your every day car or you are trek more than 10K a year, definitely go with non-RFTs. Advantage is they can cost half as much and last 2-4 times as long. The disadvantage is you may lose 2-10% of cornering grip (depending on temperature and dryness).
Unless you are rich or race with a sponsor, it's probably not in your interest to use RFTs.

And just so we are on the same page here:
RunFlat tires are not necessarily rapid wear tires. And the opposite is also not true - that Non-RunFlat tires are good wearing tires.
The wear properties of tires is independent of whether or not the tire is a RunFlat - as is the traction properties. (Although it is true that many RunFlats only come in high traction varieties, which also means they don't wear well.)
I hope that clears up the distinction.

Yes, tire life and traction are determined by their ratings. The price anyone pays for the higher ratings is generally higher. Also, the price one pays for the Run Flat extra feature is generally higher than the same tire with the same ratings.
However and from my experience, the ‘feel’ of the Run Flat tire for an equal rated non-Run Flat tire is different. It ‘feels’ like the Run Flat tire affords better traction, but a stiffer ride over bumps. I don’t have anything statistical or accelerometer ratings to support this. They are simply my observations.
Don’t think we ever left the same page, but happy we are back on it again now.
