Yea, putting in an M motor is only a small part of the M...and if you're seriously thinking of spending $8K and shipping the car to NY for this work, add more to that cost.
I believe the best advice I'd offer is to become happy with your car and save your money.
In NJ--Tierney's in Montclair, Sept. 25, 7:30 p.m.
In NYC Sat, Sept. 30, 8 p.m. at Broadway Comedy Club! Sat, Oct. 8, 6 p.m. at Greenwich Village Comedy Club.
Comedy can be a great cheap date!
Mangofy your E46!
