Replacing seat/s is a good plan. Or go to Zellers and by a pillow for 4.00. Only after Bandi or a qualified mechanic says your Golf is good for another 60K or more.
If you are hell bent on spending that 25K, I would look at a Nissan Versa. Not 'leading edge' but well rated and shares it's platform with the Renault Clio. Renault owns about 49%? of Nissan. (It wasn't just a one night stand) Go for the manual trans if your wife will approve. Then again, if mostly in town driving, not such an easy choice.
I rented a Nissan Rogue, (love the name) last summer for a trip to Oregon. I wanted a Versa but they were all out. The Rogue was good, but CVT transmission is not for everyone. Good on the highway, but offroad it just revs and sits there for a while. Gas mileage was awesome. The Rogue did not have good rear visibility, like a lot of modern cars. The Versa is somewhat better.
I would also look at a new gas or diesel VW if it has a very good warranty, diesel probably the best choice if you're going to rack up the kilometers. Or, the Matrix, maybe even one of those new Mazdas that is almost a minivan, but smaller. I'd read the fine print on the Mazda warranty though. They had 'thermal incidents' a few years ago. That's lawyer talk for Dude my &*#$(&!@ car's on fire!
If you want above average performance and handling, the Versa may not do it, but you might save 4K or so. I would still give a Versa or similar a good test drive, might just do the trick. Or keep the Golf and invest in abandoned properties, find the new Cabbagetown!
Gallery expansion? pardon rant, I needed the release after doing physical work today...
