The Elan +2 is a nice car. I was always disappointed that they didn't use the front end of the Elan, but that's a personal taste issue. It is definitely a more "civilized" car than the Elan.
That one is only bid to $12,000. It might be your best opportunity to get a nice +2 On the other hand, you're up to your elbows in Europa S2 so maybe it's time to focus...
Kendo, you are right. That's the normal TC motor (possibly with a different tune from the regular Elans) which all have 2 valves/cylinder. It wasn't till the BDA that a Kent based motor had 16 valves.
