The price is good. But if you ask me, I would be a little wary of the "engine work". I would certainly try to get more specifics about what the problem was, and what was done to fix it.
Since you have already familiarized yourself with all the "horror stories", then you already know about some of the blown engines. Now, I am no expert, but it is my understanding, that once you get rod knock, your engine is doomed. Now, that said, I am sure a good mechanic could go in there and do $2000 worth of work and get it fixed, but again, I don't know enough about it to give you a positive answer. So hopefully some other, more mechanically experienced folks with chime in on that.
But all that aside, I would 100% go look at it, drive it slow, drive it fast, take it on the highway for a few miles, listen to the engine, see if it sounds good. If it runs strong, check the oil and see if it is low on the dip stick. If the seller isn't paying attention to that, you could find out if this VX has the oil burning issue ahead of time. Make sure the brakes work good and stop well, check the tires, etc.
The VX is a wicked, wicked ride, and worth every penny, but do check into the history of the vehicle and make sure you are getting into a solid running machine. If everything checks out, you will be more than happy.
In my opinion, the VehiCROSS is a performance vehicle, and it MUST be cared for accordingly. Everything from the leather seats and the cladding, to all of the mechanics. Make sure you care for this stuff, be religious about regular maintenance and upkeep, and put the best products into it you can afford.
Anyway, that's my 2 cents worth.
