Just drove my friend's city 98 today ,excellent drive,engine seems to perform really well with CNG.As i mentioned in my earlier forums that Honda engine has very long life if maintained regularly.Body parts can be issue coz it's 12 year old but u can get it Kabli cheap.My friend told me that that 98 city (new parts Malaysian) are selling with Japanese stamps and they are quite unpredictable
I reckon plz drive before buying and identify suspension condition,RPM stability,engine sound on low speed gearing,excel joints with full steer turns
Most importantly it shouldn't have any major body hits.
5.5 is maximum price of this model if car has no mechanical issues otherwise it'll cost u additional 40k-50k for fixing.
Bro 2005(new shape) automatic gear oil change has diff mechanism,plz check the oil level again from vitz expert.Cleaning throttle could be risky if mechanic has no expertise in doing this.i'll recommend go to some mechanic who has reputation and re-examine these issues.
