In case of the y61 vs 80 series, I personally like the y61. Y61 drives and handles better, has better braking and is more comfortable. Both the vehicles are very solid mechanically, body / interior parts for both are mostly available used, regular maintenance parts are easily available from markets in Lahore and Karachi. Maintenance / running expenses are similar for both the 80 and y61 and to maintain either of them you need to make use of both used and new parts.
