Superb 2.0 tsi or 1.4 tsi

Hi, currently running a 20 year old CRV, which has served me well and am finding it hard to let go of but it needs ac system for £1100+ repair, seats ripped and tired all around. Only option I've found that I thinks suits me is a Superb, either saloon or estate are fine. My budget is £8-12k, UK.

I do about 8k miles/yr, mostly short runs and commutes, with a 1-2 long runs/month for weekend trips away (200mile return trip). I'm currently on 2006 diesel crv, which is fine on my short runs as it doesn't have all the modern faffery that plagues new diesels. I'm thinking next car will be a 2016-2018 superb tailback, either 2.0 or 1.4 tsi.These seem to be priced £8500-£11500 with 70-100k. Seems like a lot for that mileage and age though.Is the 2.0 that much better? It's a dad mobile for DIY, ikea and tip runs but a bit of oomph wouldn't be the worst. I like hastle free, cheap motoring.

Thoughts? Thanks!
