You lucky guy getting the 1st gens all we ever got in the US was the 2.5 RS
The Mk1's were very, very different to the later cars... not much power (only a bit over 200bhp) and quite softly sprung. Mine was Mica Blue, and had 205/55/15 tyres IIRC on gold forest Speedlines - you get 225/40/17's on a shopping trolley nowadays
But the handling on poorly surfaced British roads was just sublime - so much suspension travel and so compliant you could ignore even the most pock-marked surfaces and just keep your foot in.
And the adjustability off the throttle was hilarious - fly up to a corner, turn-in hard off the gas (or a bit of left foot on the brake), wait for the rear to slide, and when you had the angle of attack you liked, simply jump on the gas and hold perfect 4 wheel drifts on a neutral steering angle... unless you were completely useless behind the wheel (or completely unhinged!), they were pretty much uncrashable.
In the snow, they were unbelievable - more effective than a 4WD SUV in anything other than really deep stuff as the Impreza weighed half as much so actually stopped (with the ABS fuse removed). And an LSD at the rear, so huge oversteer everywhere. If the weather forecast said snow I used to set my alarm for 4am so I could go for a hoon before the roads got clogged up with morning traffic
Mine would do donuts on wet tarmac as though someone had stuck a huge nail through the bonnet and was just spinning it round.
I loved that car so much... but the fuel consumption was horrendous (often in the low teens) and ultimately I clocked up 15 speeding points in it in 15 months and was lucky to get sent to the US for a couple of years as I'd likely have been banned otherwise.
