Got a price of €454/£380 to have the VW rear parking sensors retro fitted by the dealer, is it worth it? or shall I go for another brand around 50% less?
I wouldn't bother with a camera, the parking sensors that ship as OEM are really good and I've never found myself in a situation where I've thought 'if only I had better visibility out the back'. It's a gizmo and if that's your thing, it's a bit of fun but to replace the 310 just for that seems a bit much IMHO.
Watch the fitting though, a colleague had them retro fitted to his GT and the dealer didn't do the best job of setting them flush and every time he washed the car, he'd snag them. Eventually had them sorted out but just check carefully before you drive away.
I can't live without them in London. Everyone is so impatient and if you want to save yourself having some impatient a-hole shoving past and nearly hitting you, you've got to perfect the 5 second parallel park.
