I went to a Stealth R/T (almost the same exact car) to a MB, small world....PM me if you have any specific questions about the comparison. I still miss it but will probably have a 3si TT in the near future because I absolutely loved that car and have a huge soft spot for them. Anyways Ps2cho hit it on the mark. You can get a great w124 for $2500 but be prepared to spend a bit into it if your budget is 5k, same thing to be considered if you were getting another SL from 90-94 but the MBs will last much much longer if properly maintained. Even a w201 or something from the mid 90s might not be off mark, but with any car that old you'll hit repairs. Case in point, my 3si, I redid the timing belt, all hoses and plugs/wires etc and was dead reliable for 30k until some guy nailed it in a snowstorm
. It's just a matter of the car being that old more than anything, look for records.
