Actually the price depends on various factors such year production, year registration, mileage, appearance/exterior/paint condition, interior, service/repair/maintenance record, specs (such as CD Changer, leather seat, leather electric memory seat, park distance sensor, TV/Navigation, some with sport package such as M-Sport Body kit, Sport Rims/Sterling, Sport Suspension, etc), number plate.. but average selling price I checked recently from various sources are as follow as per Oct 2007
96/97/98: RM 60-85K
99/2000 : Rm 85-110K
The 528 stop production around Sept-2000, and therefore some of them is recond with registration anything between 2001-2005. Of course with excellent condition and low mileage and expensive number plate you would have to pay a little bit higer than the average price, at the end it is subject to demand/supply and how desperate the buyer/seller at that transaction time.
Also some suggestion from other member before that you will need to spare another Rm5K for service and get the car in better shape after purchase such as replacing some of the tear/wear parts.
Insurance will be Rm2-3K without NCD, RM1600 for Road Tax, and another ~RM1K for JPJ inspection/transfer/loan application.
Also good to have a good trustable mechanic to do a quick check before you pay. If your car is just a normal look, than you might consider another:
RM5-15 K for some nice sport rim and tires
RM2-4K for some M-Sport body kit works
RM2-4K for latest lighting system LED and Angel light
Hope this helps..
