The 911 is an '84 or '85 3.2L Carrera (there was never really a factory 2.8 for the street (notwithstanding the '73 RSR of which some were registered for road use) – only late 60's/early 70's race motors). It has motronic injection, which makes it a 3.2L – the previous model, the '78-'83 3.0L SC had CIS mechanical fuel injection. The round switches and AC control panel (center console) have the earlier, conical shape which was changed to a slightly more modern bulbous design in 1986. The 'Porsche' script on the rear reflector was also changed from black lettering to a translucent pattern in the reflector for the '86 MY. The Fuchs wheels appear to be 16 X 6's in front and 16 x 7's in the rear. A factory M491 'turbo-look' option would generally have had 16 x 7's in front and 16 x 8's in the rear (these can be distinguished relatively easily by the amount of 'dish'; 16 x 6's have no dish while the 8" wide wheels have a nice amount of dish) for 1984 and 85 – the later turbo-look cars had 16 x 9's. The flares were only welded onto the 930's on earlier cars (I don't remember when the change was made), but the later 930's (and I am pretty sure the M491 turbo-look optioned cars) all had one piece quarters and fenders. Even if they were welded flares, though, the weld is way up in the quarter panel. It is easier to feel on the fenders in front as the added flare sections were smaller so you don't have to reach in as far. That said, on factory cars "feeling" the seam under the undercoat was tough. Based on the wheels, I'd say this was a regular narrow bodied '84 or '85 3.2L 911 Carrera with flares added later.
