the carb is just code for: i just can't jump in the car and start it up --it's always a problem getting it going once it's been sitting for a while. I have a first gen SLK 230-- 1998-- and it's the most dam reliable thing on earth-- always starts-- never anything a problem-- granted-- it's only 20 years old; not 50... and it goes to the mercedes dealer every other year for a total service-- that's what i need for my firebird-- a more reliable drivetrain, and a guy who can take it in and make sure it's doing well-- i need to get a cool looking classic with modern drivetrain-- and a guy in Chicago to look after it-- i put my firebird up for sale for $19,500 and will see what happens...
