Top Gear tonight: Merc 190E, BMW M3 & Sierra Cosworth for under £5k

Top Gear Super Saloons for under £5k Here we are at week two of the latest series of Top Gear already, so as ever a reminder that the boys are on the box at 8pm (BST) tonight on BBC2 and – to speak in TG – the footballists aren’t on tonight so you don’t need to Sky+ one or other. What’s on offer this week? It’s super saloons for under £5k this week with Messrs Clarkson, Hammond & May going out and grabbing some high-preformance saloons for under £5k to see if they can ferry the brood and offer high speed thrills to boot.
