Not speaking to this car in particular, but if you ever see an Evora going for cheap because the engine is blown, buy it. Most people would not bother with such a car, but if you know how to work a wrench it is a cake project. That engine is a $1000 item -- i.e. good used condition -- and is available anyplace, and swapping it in is the work of a weekend. Even buying a new crate engine from Toyota is likely not more than a few thousand, though I admit I've never bothered to check.
Just my two cents.
I'm surprised a dealer would bother fixing a blown-engine Evora, especially a dealer with one Lotus tech, and which sells a slim handful of cars per year anyway. Not knocking them; I wish 'em luck. Thanks for the info, Maru.
