The Vauxhall 10-4 was the most astonishing car produced by the former GM U.K. brand in the 1930s, combining radical engineering with mass-market appeal.

Slap a few Nürburgring stickers on it, treat it to a 13bhp power hike, and then charge £22,000 to any polyester-clothing enthusiast gullible enough to buy it, that’s what. Shameful. Makes me sick.

The Vauxhall Wyvern was priced to start at £350 (approximately $17,400 in today’s money) or a few pence short of £448 ($22,300) including U.K. Purchase Tax.
