Pros & Cons:
Waja:
1. Easier to maintain, spare parts plenty even for Campro model.
2. Forget about people saying no power (that only applies for the automatic model), but if u upgrade the stock standard exhaust manifold to those after market extractor and remove the CAT, the low end power will increase.
3. Better resale value.
4. Parts interchangeable with Mitsubishi Lancer MX or FTO (plenty of future upgrades).
5. Many Waja clubs to join, WPC, WRC... etc...
Optra:
1. Expensive maintain because it is a Korean car and most parts are fully imported. An oil filter costs RM 35, air filter another RM 50 and most Japanese parts won't fit it well without mods.
2. Lousy resale value - expect to drop more than 60% after 3 years of ownership. Ask any Kia/Hyundai owners out there.
3. Clubs? Are there any?
4. A 2005 model would probably be a lemon because after long exposure to our local climate, plastic parts will start to creak and crack (u won't see it until a year or so).
5. How reliable is the Korean engine? Quite actually but don't expect to bolt-on turbo or do crazy internal mods because unlike Japanese cars, parts are hard to come by. And even if u manage to track down a used chop parts, u can't use most of it because Korean cars are LHD!
BTW, Proton also recycle unsold models as new. Eg. A 2007 Gen2 could be a 2005 or 2006 batch left to bake under the hot sun outside Proton Edar without u knowing it. Why? My bro's Gen2 2007 model is falling apart, majority due to cheap plastic parts cracking here n there.
A side note: Don't buy used Japanese cars if u r not a motorhead or really don't know how to maintain an old car properly. U will end up spending more money than a new one. Seriously. I drive an 18 year old Mitsubishi Galant VR-4 and so far, I've spend more than a new Perodua Viva 1.0 Premium to maintain it as well as upgrade many worn out parts with performance ones. Yes, it will definitely eat many new cars for breakfast, lunch and dinner but u need plenty of patience and money.
