I'm considering buying, from its 3rd owner, a 1986 190E 2.3-16 with 139k miles. He has the paper work of the last 6 years he's driven it. Before, it belonged to a buddy of his.

I wonder if the price list for parts on this car somehow resembles that of the regular 190E, or this is a totally different animal and has an outrageous price list for everything? Is the 16 valve as reliable as the other MBs? Or due to its high performance, is it prone to more failures?
I'm not into twiking or racing this kind of cars, I;ll try to keep it OE, and use it as a daily driver.

I'm test driving it tomorrow evening, please let me know the major things I should look for and the typical parts broken or missing on this model. Thank you.
