Early cars got rubber mats but most cars now sport carpets, along with an aftermarket steering wheel; original wheels can still be sourced if you prefer originality. The engine and box in the car are fine, turn over etc but I have never tried to start it. Thank you for contacting us! There are no knocks, whines or clonking from any part of the drive train or suspension. Use a magnet to check for this, focusing on the sills and the rear spring mounting boxes. It runs really well with good gearbox and overdrive working perfectly.
