Cost seems to be daft atm, my golf gti 2 years ago manual with metallic paint and pan roof was £27k I think. Now for a similar spec it’s £35k. Wtf is going on?
But no one would pay £35k list - discounts on the GTI are big
Discounts haven't risen in line with the price rises though, so the car does cost more today.

The base OTR price of a GTI PP has risen by just over £1000 in the last 6mths, and discounts have dropped. For every £1000 on or off the total OTR cost, it equates to circa £25-30 per month on a monthly payment, so buying today straight away a Golf is £25-30 per month more expensive than it was, and that's before you start thinking about discounts, adding options etc.
I got mine back in December 2018 before the two price rises, and it costs me c£465 a month over 4yrs with £1000 in from me. Compare that to the person a few posts back who pays £365 over the same term also with £1000 in, then on paper theirs is 'cheaper', but mine has/had £6500 of options which normally on a PCP equates to c£185pcm on the monthly payment. So with the bigger discount I got back then and lower initial OTR cost, my car is actually (once the maths is done) cheaper than his/hers.
So Moots is right, the base price of a car has risen, discounts have dropped, and a Golf today is a more expensive than it was a short time ago, and drastically more expensive than it was 12months+ ago.
As said, you cannot judge if a car is a good deal just by looking at the 'monthly' price alone.
