I Hv both liana Lxi and cultus. There is no comparison between the two. Liana is far superior then cultus but yes when it comes to maintenance liana is expensive to maintain then cultus. I think we make mistake in comparing the cost of maintenance of liana with cultus. It wd b fair if we compare the maintenance cost with same level Cars like city or corolla. For sure u will not get corolla or city of same model of liana in same price . Most of people make mistake in buying liana I very cheap price . Usually those are not maintained well and u end up spending much more. Now the difference between Lxi and Rxi. Lxi has in addition, the RBS brakes, factory fitting alloy rims, matching handles & side glasses. I wd suggest that u better go for upper models like 2009 onwards. Most of lianas of 2006 & 2007 are in poor condition.
