This is the second part of a two part series on the best used luxury cars . -LRB- AOL Autos -RRB- -- Recently , Consumer Reports magazine issued its list of best and worst used cars , and divvied them up by price range . The Porsche 911 has several versions , but all have been annointed with the `` supercar '' appellation . Using CR 's recommendations as a guideline , here is a list of some of the best used luxury cars currently on the market in the $ 30,000 + price range : 2007 Acura MDX The newer MDX is classified as a crossover SUV , but it 's a deluxe version . It was all-new in ' 07 , and was built on a proper platform -- as opposed to being adapated from the Accord passenger-car platform . It also came in three flavors : Base , Technology and Sport Packages , and all three were powered by a 3.7-liter 300-hp V6 . The voice-activated navigation system is a nifty feature , as it comes with rearview camera and AcuraLink satellite communications with real-time traffic data . AOL Autos : Used Acura 2007 BMW 328i sedan The 328i is another sleek , finely-tuned and beautifully-designed driving machine , offering sporty performance and Euro-style luxury . It is widely considered to be the definitive `` sports sedan . '' The '07 328i was propelled by a 3.0-liter 230-hp inline six-cylinder engine , which you can find mated to either a six-speed manual or six-speed automatic transmission . Consumer Reports also recommended the 3-Series coupe and convertible that joined BMW 's model line-up in ' 07 . AOL Autos : Used BMW 2004 BMW M3 The M3 is the top-of-the-line , high-performance-tuned version of the 3-series coupe . Performance power , therefore , is much higher than the other 3-Series editions . It came as a coupe or convertible , and churned out 333 horses . The M3 is often favorably compared to the Porsche 911 when it comes to quick acceleration , crisp braking and taking tough corners at brisk speeds without breaking a sweat . 2007 Infiniti FX35 Well , the marketplace surely is not lacking for luxury crossovers . Here is yet another one that appeals to luxury buyers with its balance of SUV-type spaciousness , pampering amenities , deft handling and burly engine muscle . For ' 07 , the FX35 was a two-wheel-drive vehicle powered by a 280-hp 3.5-liter V6 and a five-speed automatic transmission . AOL Autos : Used Infiniti 2006 & 2007 Infiniti M Infiniti 's M series is another winner , which seamlessly synergizes sleek styling , aggressive engine performance and a bevy of luxo-line amenities . It comes in both the M-35 and M-45 . During the last used-model year , ' 07 , the primary distinction between the two was that the M35 was powered by a V6 that kicked out 275 horses , while the M45 muscled up to a 325-hp V8 . Luxury features included standard leather seats with heating and ventilation , and optional 10-way power adjustments for the driver 's seat . Lexus Just like in the $ 24,000-to - $ 30,000 category , Consumer Reports recommended a slew of world-beating used Lexus models in this segment : the ' 06 - '07 6-cylinder GS RWD ; the '07 GS450h Hybrid ; ' 05 - '07 GX ; '07 IS ; ' 04 - '07 LS ; ' 03 - '06 LX and ' 06 - '07 RX .
