They are defo dropping in value, D4s now well under 10k, D2s are getting thin on the ground, cant remember last time I saw a D1 200 or 300 on the road or just in somone driveway.
As usual some people still think their D3 is worth more than a later D4! same as the last of the D2s were still being priced at 10k a year or so ago when D3 were cheaper.
Ur so right ref values of D3s where some think there worth we’ll over £10k for a 06 model
Still see a few going between £2-3 on eBay , then read down the listing and says , may need new mechatronic unit
Time to run for the hills, lol
