I'd be happy with 4k for mine....I have a dealer trade in of 3k pegged for my 07 GT, just 1 year older, but it has over 20,000 on the clocks (Oh, the horror, the abuse! How can the machine stand to be ridden soooo much!). Likewise, very clean, always looked after, ACF50'd to the hilt.
Still, I only paid 5k for it in 2009, so its lost £500 a year.
Compared to my last bike, a BMW R1100RT...trade in at 69,000 miles was £1800, £700 less than the purchase price, had it just over 2 years & did a similar mileage per year. Of course, if I factor in the astronomic BMW repair costs it comes to around £1200 per year lost.
Repair costs on the Vee so far? 1 clutch slave cylinder seal...£5.26.
No. of AA recovery trucks required? BMW = 3, Vee = 0.
