Right, dont tell no one (lol-it's a public forum!)
I found out some info on the car today somehow
It is confirmed as an Altezza RS200
Regd keeper had it since 10/03/2004. A Mr I Khan in E17. But a new V5 has been issued very recently...The reply address from the ebay seller is Roohi Khan. So this is fine.
So, the seller most likely has bought the car as a trader recently, bought a Odometer/speedo clock with less miles on (maybe-no evidence to prove this end), and then installed it making the car appear with lower mileage...And then, this is backed up because the car was broken into and all of the paperwork/history was stolen.
I think the car is generally legit as an Altezza, but the mileage could be doubted.
The first paragraph is fact, the second paragraph is opinion.
i am going to edit this above info in 24 hrs.
