both shot to legendary status in early 90's
both has many die-hard fans
both were GT/Touring car legends
both were road versions of race machines
both handles great
and both are available as used vehicles in mint condition(the M3 is very slightly better maintained by the owner) priced within my bank account's reach, with these two cars's salesman in constant contact on my cellphone.
please help me decide...
