turbo cabs seem difficult to price imo, i've seen som go for peanuts and some do really well, yours is a good spec, suppose you could try it on ebay
I paid 1750 for my turbo cab last year its a summer svp edition, half leather 72k power hood all the other bells and whistles, I'm happy with the ammount I paid as its not a bad en, although I've spent prob close to the purchase price again on a few repairs and nice bits for it
Would be a shame to break yours but its often the way to go
