Sold our RS Clio thru them a couple of weeks ago.
They offered £12987 on it, WBAC were approx. £11500 and the dealer where we were looking at a new MX5 offered £11k.
Turned up on a Sun morning and within 30mins the deal was done less their £78.50 admin fee with the funds in our a/c on the Thurs as promised.
Our car was detailed by me regularly and was mint in and out but they did say it needed a full interior and exterior valet for £100. After I laughed, the guy spoke to his underwriter (I believe it's the underwriters decision that's final) they just paid us the full on-line valuation.
Oddly enough, they are owned by Manheim and every car they buy goes straight thru the block, ours went thru Mon 19th Oct and I was nearly tempted to buy it back because there wasn't a prayer of it making nigh on £13k at auction.
Overall, 10/10 from us.
