I'm not a buyer on that car, but if I was, $13-14k. Engine scares me too much. They love to explode, and it's $12-15k to make them right again. Too much risk for a car that will seem slow as crap for me too. I'd rather get an M30 powered Euro 635CSi and have all of the looks and none of the mechanical worries.
You wouldn't be giving up much seat of the pants performance either I don't think.
The older I get the more I appreciate the search for the right car. When I was younger the money burned a hole in my pocket and I bought the first thing I found.
Searching for a nice Euro E24 would be good times.
