Chatting to a mate yesterday who drives a VW Tiguan. He has this car on a 48 month lease and pays around £250 per month including servicing - he said he doesn't like having capital tied up in a car but, more importantly, he can drive a better car.
Wife has a Tiguan and I keep on eye on these things - while there are PCH deals from time to time, that's pretty cheap for a Tiguan. He may well have had a hefty initial payment, which people always ignore when they talk about how much their car costs. The cheaper deals are usually very limited on mileage - could be 5K/yr - although if the finance is through VW then their excess mileage charge isn't too bad.
They are pretty strict on the car's condition when it gets returned - you see a lot of complaints from people who think they've been unfairly charged. As suggested above, if you have to return early you get hit - VW charge 55% of the outstanding rental, but some finance houses want the full amount.
One thing that's put me off so far is you're not in control of the timing - at the end of the deal the car pretty well has to go back. In theory you can buy the car but the price is usually high, or you can extend the lease, but VW often whack the cost up. So you've got to have something sorted well in advance and there might not be any deals around at that time.
Is PCH cheaper than PCP? I think it can be be if you get a deal on PCH but at normal prices they should be similar. We started off looking at PCH on Tiguan when we got ours 4.5yrs ago because I stumblesd across adverts at £89/mth. But that was the baisic model in a flat colour, 2yr deal, 5K/yr. Plus VAT. Plus a big initial payment.
The model we wanted, on the terms we wanted, was a bit over £300/mth. But on PCP is was available with £6000 discount. Trying to guess its value at 3yrs old I reckoned there was nothing in it, so we went the PCP route, although we pulled out of the PCP to save the interest cost. If we'd needed the finance then PCH would have been cheaper (but less flexible). We got the 2014 Jazz on PCP as it was 0%.
