I have not had this car for long, so cannot really comment on reliability. Still a quick car for it age and really fun to drive. It takes you back to when cars were cars with out assisted brakes or steering. A super fun weekend car or daily driver but does require skill and concentration especially in the wet.

I really love the bmw 540i. Performance is great but you pay with the economy of the vehicle. Exhaust sound is average and really wish they had put in a slip diff like the M5. This car is made for the highway with tons of talk. Long journeys are a breeze and the fuel economy is great if you keep the car in the low rpm range.

The car has been reliable for me but I have had to replace parts on it. I have seen the check engine light a couple of times and have had to buy a new maf and clutch fan.

Overall I am very happy with the car and have no idea what I would replace it with if I had too. For the price you get great performance and luxury.
