But the same money can get you into newer stuff, on a newer chassis platform (MQB vs PQ35 here) and (in the case of that Leon I linked above) possibly even newer tech like Android Auto, Apple Car Play etc. Parking sensors and sat nav isn't something to get excited about on a 10k car.
You say that but I have none of the above. I don't particularly care for them either but CC is definitely something I'm looking for now, with the motorway miles I'm doing atm.
The seat is definitely a contender, found a nice one that got me thinking.
