Yes it is overpriced...but then I think everything is overpriced
This sort of pricing is effectively killing the classic car market, at least at the entry level, the younger end of the scale. To me, your viva i a nice clean example needing some work, jobs that can easily be done, but the jobs themselves can put people off, especially the clutch although that is the easiest to do. The headlining will be expensive and a *Bleep* to do as it needs the glass out to do it properly and the door lock is an MOT fail and will need a new lock probably, not easy to source. All this points to is an MOT'd viva in fair good condition, which I myself would happily pay £600-£1000 for. A bit low? Well thats because i think these overblown prices that people are asking for viva's are killing the cars. Back in the day, when i started my viva journey, viva's were free... even GT's didn't get over 2k and that was fine, just about what it should be, but now, all these massive prices are forcing people out of the game, rot-boxes on ebay for 1k plus??? ridiculous. Less viva's will get restored, used and loved, because people simply cant afford them, why pay around £5000 for a viva when there is far better and more exotic machinery around to be had for that price? The grass roots viva-ing is no more, it is now the pass time of the middle-class, and as such is killing the model. Don't get me wrong, I guess if you can get the money that you want for your car then great, fantastic, super....but you can't can you, not so far. Drop the price a little, or get the jobs done. It's simple...even if you do just the clutch, it will only take you an afternoon.
I'm not here to cause offence, I just sit here fuming at the way money drives everyone . . . classic car dealers are to blame largely i think, they stick an over inflated price on an old knacker, some idiot pays it and everyone else thinks 'oooh .... i can get a lot of cash for my old viva' and then it starts, and you get honest sellers like the OP trying to get at least in the ball-park of these prices and is sat left with no one wanting his car... whereas if he had a more realistic price on it it would fly out the door....probably to a classic car dealer who will double the price
I guess that's the way of it these days... but there you go, I'm not bitter
