£4400 cost to change?
Get it done!
My initial thoughts when seeing you’d only done 2k miles was “ouch, that’s going to be massive depreciation for such little use” which is something I’m very familiar with myself.
Then I pondered the cost to change for almost a whole nanosecond and came to the conclusion I’d probably chew their arm off for that.
The GTI will cost a bit more to run but not heaps more and you’re not doing massive miles so will hardly notice it.
£4400 for all the extra satisfaction of owning the GTI which will also be worth more than the 1.5 when you come to sell it negating most, if not all of the cost to change.
I look forward to seeing the photos!
