Looking at a 98 CLK320

[JordaanDMC-12]

Hey all,

One of my sales managers is wanting to let go of his 98 CLK 320, it has something like 345,000 miles and has been sitting on the roof of our dealership since I started working here about 9 months ago. The paint is peeling and the interior needs some TLC but I didn't know how it ran until yesterday, he gave me the key and said to try it out for a few days... I honestly thought he was just going to give it to me because he just wants to get rid of it but he said he'll take whatever I offer so I'm interested.

When I started it up yesterday it ran really ruff and warning lights flashing and going crazy but after idling and driving it around the dealership it ran great! No warning lights and engine/trans felt normal which was surprising for 300+ thousand miles... I'm pretty sure I'm going to buy it from him but wanted to pop on here and ask if there is anything these specific cars are known for problem wise? I've only ever owned w124's and w123's so this year range is new to me, any advice input would be greatly appreciated!
