Got a 1985 mercedes 190e used first mercedes need info

[movenwheight]

Ok lets start with telling u what I got and paid for it. 1985 mercedes 190e 2.3 liter 4 speed automatic mileage says 90,000 but the odometer doesnt work . Its interior is rough but thats an easy fix with a vacuum and some seat covers the exterior is great for the age its pretty. The motor sounds fine hard to start when cold or hot guessing cold start fuel injector is going bad. Transmission seems fine suspension needs help and the throttle seems unresponsive to my foot its proably me im use to my motorcycle .

First question should I upgrade the intake and exhaust ? Im a speed freak but I dont think ill notice the upgrades with the automatic transmission.

Next question should I even put money into the car I love the way it looks and I know benz is a great company and there very reliable and im a sucker for older vehicles and sleek lines .

Third question suspension upgrades should I upgrade or is the original just fine ? I know this goes with performance but I think they are seperate.

Last is how long do they last and hold up to the everyday use and abuse ? What can I expect out of a motor as in mileage with frequent oil changes and not stomping the pedal through the floor board.

Notes on me. I want a better sound from the vehicle not an obtrusive annoying sound and I want to keep the car because I like it and the name. My neighbor had one when i was a kid and ive always wanted one since.

Any thoughts would be appreciated as long as they are honest.
