I bought my Tiago XZ+ brand new. Done a few hundred kilometers so far.
On city drive, I received a mileage of 11- 12(kmpl) with AC and on highway 16-17.7(kmpl) with AC. Far to early to comment on performance, will update after first three services. AC is very good. Design is attractive. Very good music system comparable to luxury cars like Jaguar. Easy to drive. Gear-shift like maruti (need more refinement). Good meter console. Adequate spacing for 5 persons. Boot space is okay-okay.
Follow me light in Tiago is helpful. Very good Ground clearance, approach angle and departure angle. Ideal for village rides. 3-cylinder engine, idle vibration is obvious. Sound insulation is Good.
