Since Lexus is a Toyota brand, great quality and reliability are expected as standard. And, according to owners, the Lexus IV is no exception and no major issues have been reported.
Lexus is a luxury brand and that combined with the reliability and durability of the Lexus IS vehicles leads to the higher purchase price and the slow depreciation. Buyers, however, receive great value for their money, so high price is justified.
Owners say that parts and repairs of their Lexus IS vehicles are, indeed, more expensive than those of cars in lower classes, but the quality of these vehicles is so high, that they rarely need to be taken to a mechanic. So, apart from expenses for the usual check-ups, done as recommended by the manufacturer, other maintenance costs are rare.
