Pros - Peppy and fuel efficient engine, decently euiped for base trim, good ride comfort
Cons - Compromised rear headroom, front seats lack proper lumbar support
Could have easily been the perfect sedan! I love the way the new K5 looks, especially with those flash like orange running lamps. The overall design is very sleek and elegant. to match the looks it also gets one of the best insides in my opinion. Eventhough i got myself one of the lower trims, it does not feels trimmed down. Everything that I use come as standard fitment in the car and the only thing I felt was missed out is the second row aircon vents. The engine operates silent and efficiently and is a good choice for expressway drives at good speeds. the only thing that it shough have had more of was rear bench headroom, as some of my colleagues find their head rubbing against the roof at times due to the sharply slanting roofline. Howie is an awesome sales person. Got the car I wanted at a great price. Got the car delivered on the promised date without any dealys whatsoever.
Pros - Edgy design, super premium cabin, lavish equipment list
Cons - No very involving to drive,
You could never ask for more! As far as I'm concerned, nothing looks even remotely refreshing as the K5 in the segment.It was an insatnt purchase for me while at the dealership. I bought the gt line as it featured a bit more agressive design. I am also a bit sad at the fact that the GT line only gets differentiated on the basis of styling and does not get any performance improvements. That said, the stock engine is pretty spritely and gets the job done. The cabin is executed really well and the red accent lines and gunmetal finish at certain points given it that added premium feel. The infotainment is suck a delight to use and the Bose premium audio system is simply the best one on any car that I have owned prior to this car. Got hold of my K5 GT pretty quick. I thank Rivan, my rep, for making everyhting quick and easy for me. Such a pleasure to have worked ith this guy!
Pros - Great pricing, Premium design inside-out, top class equipment.
Cons - Found nothing to complain as of now!
No con on this one! You wouldn't find a better sedan at this price tag. I was pretty shocked on seeing the list of features it comes with as standard. Both the exterior and interior looks stunning and new age. Drving this car around town is such a breeze as the steering is pretty light and the engine is delightfully refined. The transmission is also quick as hell and shifts through ratios very quick. the steering feels nice to hold on and the media screen is set at the line of sight making is easy to use while driving.The unit itself is a smooth and clear one with an intuitive interface. Everything about this car is user friendly and that is what makes it stand out. Rebecca was fantastic. Very upfront, not pushy at all. Also very easy to talk to during the whole process.
