My own reason was because I asked the insurance company for a quote and they gave me a really good one, I wasn't expecting it at all. I was expected to be told that 'we don't insure that type of car' but I was surprised really when I found out it wasn't going to be overly expensive over my current BMW.
It was within price range at the time and I just bit the bullet. I always liked the shape/styling of the DC5, the reliability of the Honda brand and the K20 engine really made me want one.
I had a Pulsar VZR before the BMW which I loved and still have, well, the girl friend drives it at the moment but no biggy! I wanted a change and pretty much nothing on the market tickled my fancy, evo's and scoobys are a dime a dozen plus running costs and reliability issues made me steer clear.
The DC5 just kind of fitted into the category of something I wanted, rare (enough at the time), fast, reliable, not economical but I mean, it's not that bad and it's basically a car I've always wanted.
My first thoughts when I sat in one was, wow, there's nothing here, I came from a BMW loaded to the brim full of extras, buttons and displays and everything everywhere, but the Integra had a different feel, straight up, focus on the driving experience, none of this buttons on the steering wheel and a hundred million different settings for your air con/seat. It was perfect. The BMW took away from my driving pleasure, on the motorway, just hit the cruise control button and that's it, whereas with the DC5, it's completely calling for you to drive it on, handling is superb, out on track it's a different animal and when VTEC kicks in (y0!) it's something else. Still brings a smile to my face today.
As for other cars I looked at, at the time, none really, some thoughts did go through my head.. including..
180/200sx rear wheel drive turbo power.. tempted but hard to find a clean one that wasn't ragged at the local crossroads to within an inch of its life
BMW 325/328/330/M3 after changing from the Pulsar to an E46 318 Coupe I really just didn't want to stomach another BMW, plus the price of the M3 and I'm sure the insurance of have been a barrier to me getting my hands on one
Toyota Altezza.. rear wheel drive fun and the bottom falling out of the market made these very very affordable, but they're gaining a growing reputation over here as the new AE86, I know the Champ White, Red H's and the Type R badge on the back of the DC5 don't do me any favours, but the Altezza seemed slow, heavy and just too dull.
