Are Mitsubishi eclipses expensive to repair? in comparison to a toyota?

well, toyota isn't too much to repair compared to a lot of other foreign cars besides most Japanese. Mitsubishi shouldn't be too much to fix either.

I don't think it cost any more then a Toyota, it is just that they need repair more often.

well it depends on what kind of mechanical problems are wrong with the vehicles. toyota or mitsubishi. i owed a mitsubishi at one time and i had alot of mechanical problems with it like the engine went out like at 70,000. i put a rebuilt in it which was like 2400.
then my axles broke on both sides which cost me like 1200 each to repair.
then after all that some idiot ran a stop sign and totaled my car out which i think was for the best.
now, i currently own a 2002 toyota celica 5 speed with a trd package and haven't had any problems with it.
toyotas are the best #1 selling vehicle out on the market.
yeah it just matters on what needs repaired.
all vehicles are costly to repair because the mechanic is getting paid like 60.00 a hour.
good luck.
i hope you really go with a toyota.
