A few pointers. Dash - depends on the problem. Door interior - fix or replace depending how bad. Door shuts - it's supposed to. What do you really mean? Neon - Soarers don't have them, so they are add-ons. AC - the fan is supposed to work when AC is on, might be bearing or pump noise, you need to listen under the bonnet to get a better idea. Seats - up to you, or some of the imitation leather covers have been used by some members. Brakes - might be worn or just have noisy pads - change them. Hot air - is the heater on? Is there a hole in the firewall? Hump sound - sway bar bushes, or LCA bushes or both. Car slow - could be many reasons including too high expectations. Petrol smell - car might be running rich for some reason, probably also related to the issue above. Speedo - language can't be changed, print the translations and keep a copy in your glovebox. Dash monitor EMV - some things can be changed. Height - changes slowly. TEMS - should make suspension a bit stiffer. ECT - no real noticeable difference most of the time.
