how are the repair/ maintanence costs of an m5 of this gen. i have an e30 325, and it's not that expensive to fix at all. however, all the sources i've seen say the m5 is really expensive to maintain, but also say it's only marginally more expensive than the car i already own. maybe my perception of repair costs is just off because it's the only car i've owned. i dunno, but i'd like to. thanks
The older, hand-built M-cars like the E34 M5 and E30 M3 can be expensive to maintain. These cars are getting older, and things start to wear out. In addition to all of the usual E34 and E30 problems, you have the M-specific parts. Some of these are just trim pieces, but many are mechanical and cost a ridiculous amount of money.
The engine is the primary source of cost in either car. The M3 S14 engine is of course just 2/3 of the M5 S38 engine. Valve adjustment is necessary. These engines came from the factory in a very high state of tune, so they can be a bit tempermental. Neither car likes to idle for extended periods, given their aggressive cam profiles.
Mechanical condition is very important for these cars, particularly the engines. New engines or rebuilds can be extremely expensive. (Not 30k for a new NSX engine, but between 5-10k for a used or rebuilt one).
You may want to stay away from heavily modified cars. Chips aren't a problem, but a lot of people put an aggressive exhaust cam gear on the car, and this puts extra stress on the engine (my mechanic does not recommend using the cam sprocket). Maintenance is key.
I would rather have a car that was driven, but maintained, rather than one that sat in the garage. One thing to watch out for is a previous (recent) owner that couldn't really afford the car. Since prices are fairly low, people buy them who can't afford to maintain them.
You need to be able to budget at least $100/month for maintenance repairs, and have the ability to absorb large expenses if necessary.
