Around 7.5k depending on history/owners etc. It's very low miles but imo a purple convertible is not the most desirable for those looking to spend that sort of money on an e36, regardless of miles.
Don't be fooled OP by the very low mileage. The parts will all be 15 years old. I made this mistake with my second M5 a mint low mileage one, which I carried parts to. The previous one had 80000 on it when I bought it and needed far less.
Interesting one - as I said, not for me, has sold TRADE for a lot more than suggested despite missing service book (but pintouts and copies of earlier ones), and also despite being in region of posters here on ebay!
