when i had my 6, over 3 years ago - they were still very rare and people were chopping in escoss in left right and centre and it was a hard decision at the time whether the saph wne in against a mint low milage evo 6 or mint low milage escos -(both around 22K£) the dealer talked me into the fact that he'd rather have the evo back in 2 years than the escos - but now, as there are getting so many evos' they are fallin inprice (new as well as s/h) the rarer of the 2 is now becoming more salable - as a matter of interest... i paid 22K for the evo, sold it 1 year later for 18 having spent 5K on 'sensible mods and running it'( pipe, chip, fuel pump , tyres etc). i then paid 15 for the escos 2 years ago, and its still worth at least that today, but ive spent around 5K on 'essential repairs' sensors, clutch, fusebox, brakes etc ect.
dont get me wrong i'd rather have had the evo and lost a bit when they were rare than pay 12k for one now that needs bits doing to make it right again. neither are cheep to run, the evo is the more 'brilliant' car but the escos has more charecter, presence and hold value better in the long run.
